 * Name: modhandle
 *
 * Description:
 *   modhandle() returns the module handle for the installed module with the
 *   provided name.  A secondary use of this function is to determine if a
 *   module has been loaded or not.
 *
 * Input Parameters:
 *   name   - A pointer to the module name string.
 *
 * Returned Value:
 *   The non-NULL module handle previously returned by insmod() is returned
 *   on success.  If no module with that name is installed, modhandle() will
 *   return a NULL handle and the errno variable will be set appropriately.
